Abstract (en)
Feedback is provided, based on an actual drive amount of an actuator, to a command to a subsequent actuator. A control system includes a memory configured to store a program configured to generate a command related to a working position, a controller configured to execute the program, a first output unit configured to output a drive signal to a first drive portion, a second output unit configured to output another drive signal to a second drive portion, and a measurement unit configured to measure a drive amount of the first drive portion. The controller is configured to extract a low-frequency component included in the command, transmit the low-frequency component to the first output unit, correct a high-frequency component included in the command based on a signal indicating the drive amount of the first drive portion, and transmit the high-frequency component to the second drive portion.
